Filament Sample Keychain

thingiverse

This little sampler lets people see what kind of materials they can print with. The tolerances are pretty tight, so we had to sand off a bit to get everything to fit together properly. It's actually a great way to carry samples with you wherever you go. When printing the connector, make sure to use a flexible material. We printed ours in PETG, but it was really hard to stretch around the four sample cards.
